That is considered non-native here and it is very difficult to get rid of it.

The following links are in Slovak, but there are latin names of the plants.

I have found a seed mix that appears to not have any invasive plants (site in German): https://www.bloomling.de/samen-maier/bio-nuetzlingsweide-summ-summ-wiese, and it is also available in my country.

The Slovak company Novesta makes some: https://www.gonovesta.com/en/vegan-shoes Star Master / Dribble and a couple of other models are also made just from cotton, caoutchouc (so plastic-free except for the insole which is recycled rubber). Leather, rubber and synthetic material shoes are also available if you prefer that. Personally, I own a pair of Star Masters and they are pretty nice, although for my next purchase, I would choose shoes that are less flat. Also important to note: after 2 years, the heel counter is getting worn out from the inside.

Do they not licence their brand name to other companies?

Hmm… the ID editor is still light. That should be fixed asap along with the map dimming.
